Fetal movement will usually be felt regularly after the 20th week of pregnancy. Any change in fetal movement (other than a 1-2 hour sleep cycle that some fetuses have) should be discussed with your physician. Decreased or absent fetal movement may be a sign of fetal distress. Kick tests (fetal movement counts) are used to monitor fetal wellbeing. You should monitor fetal movements (not just kicks) over a period of time (30-60 minutes). There is no right or wrong number of movements. You are trying to establish a baseline of fetal movements for your baby.
Early in your pregnancy, you may just feel a few flutters every now and then. But as your baby grows -- usually by the end of the second trimester -- the kicks should grow stronger and more frequent. Studies show that by the third trimester, the baby moves about 30 times each hour.
